Abstract

Osteoporotic vertebral compression fractures (OVCF) are common and disabling. Augmentation techniques differ by access (uni vs. bi), trajectory (curved vs. straight), and implant platform, but direct head-to-head evidence is limited. We conducted a frequentist random-effects network meta-analysis (NMA) of randomized controlled trials (RCTs) with method-specific nodes (unipedicular percutaneous vertebroplasty (UPVP), bipedicular percutaneous vertebroplasty (BPVP), unipedicular percutaneous kyphoplasty (UPKP), bipedicular percutaneous kyphoplasty (BPKP), percutaneous curved vertebroplasty (PCVP), percutaneous curved kyphoplasty (PCKP), deflectable percutaneous kyphoplasty (DPKP), dual-plane UPVP, KIVA, TIVAD, and conservative care). Risk of bias was assessed using the Cochrane risk-of-bias tool. Outcomes were Visual Analog Scale score (VAS) (≤ 14 days, 1-3 months, > 6 months), the Oswestry Disability Index (ODI) (post-operative, long-term) (measured at the earliest post-procedural assessment and at long-term follow-up > 6 months), vertebral height restoration (%), local kyphotic angle (LKA) at last follow-up, bone-cement leakage, secondary vertebral fractures, and operative time. Twenty-eight RCTs (n = 3,049) were included. By P-scores, DPKP and dual-plane UPVP ranked highest for VAS ≤ 14 days (conservative ranked last), PCVP and UPKP ranked highest at 1-3 months, and dual-plane UPVP and PCVP ranked highest at > 6 months. For disability, PCKP and UPKP ranked best post-operatively, and dual-plane UPVP and PCKP ranked best at long-term follow-up. Radiographically, BPKP and KIVA ranked highest for vertebral height restoration, while PCKP and UPKP yielded the lowest LKA at last follow-up. Leakage was lowest with the Shield kyphoplasty system (Soteira), PCVP and PCKP, secondary fractures were lowest with TIVAD and KIVA, and operative time was shortest with UPKP and PCVP. In an RCT-based NMA of OVCF treatments, augmentation generally ranked above conservative care for pain, but no single technique dominated all endpoints. Procedure selection should be tailored to the clinical goal - pain control, height/alignment, safety, or efficiency - while considering patient factors.
